Game Class

The Game class represents a generic video game in the Bluetang framework.

Core Components

Responsibilities

• Launch game through GameLauncher

• Manage game window information

• Control FrameGrabber instances

• Feed GameFrames to GameAgent

• Throttle frame feed speed

• Expose game-specific API

• Register and manage game sprites

• Manage regions of interest

• Handle OCR presets

Properties

Key Concepts

Frame Grabbing

When play is called, a FrameGrabber runs in the background as a separate process:

• Maintains precise capture rate (default: 30 FPS)

• Stores image data in memory stack

• Automatically shuts down with main process

Game Frame Limiter

Frame dispatch to game agents is throttled to ensure:

• Realistic APM (actions per minute)

• Normalized intervals between actions

• Natural gameplay feel

Default limit: 2 FPS (120 APM theoretical maximum) Configure in: config/config.plugins.yml

Game API

Game Plugins can include GameAPI subclasses with:

• Game-specific utilities

• UI operations

• Image processing routines

Sprites & Regions

• Sprites: Auto-registered from files/data/sprites

• Screen Regions: Define rectangular regions of interest

• OCR Presets: Configure text recognition settings

Methods

launch

def launch(self, dry_run=False)

Launches the game and runs callbacks.

Cannot be overwritten by plugins

play

def play(self, game_agent_class_name=None, frame_handler=None, **kwargs)

Initializes and runs a game agent with specified frame handler.

Cannot be overwritten by plugins

Callbacks

def before_launch(self)
def after_launch(self)

• Can be overwritten by plugins

• after_launch requires super() call

• Used for custom launch logic
